The power requirements specified in the 910H manual are 13.8 VDC +/- 15%, which is 15.9 V on the high side. I would not feel comfortable running mine at that level, however. I would suggest putting a couple of 100A diodes in series with the + side of the power lead to drop it down closer to 13.8.... (2 would drop it to about 14.5, which is close to what you might encounter in a car with the engine running)

I am changing my supply for my ICOM IC-910H because my PS-30 is dying. I have an SGC PS-50 supply that is not regulated, per se, it is a huge supply with massive transformers. It appears to work fine, but I am worried about the fact that is starts at 16v or so.
Specifically, is 15.5 to 16v too high to safely run this radio and is a drop of 1-1.5 volts too much unregulation for proper operation?
